Yeah - we fixed PETSc [maint] to not require -fallow-argument-mismatch - and use it only with externalpacakges that need it And we do have one test box with gfortran-10 - but the test coverage with it is minimal. [mostly no externalpacakges] Satish On Mon, 13 Jul 2020, Jed Brown wrote:

You want this for PETSc or for external packages? We add it for a bunch of external packages. I've been building PETSc with gcc/gfortran-10 for months now.

Do we have gfortran from gcc 10 running anywhere? We need a check to enable

-fallow-argument-mismatch

from configure. Should be as simple as compiling Fortran which has PetscObjectSetName() in it.

Thanks,
